To w72/ 1,071,011@ it may concern:

Be it known that I, CHARLES COLLINS, a citizen ot' the United States, residing at Rockyford, in the county ot' Otero and State of Colorado, have invented a new and useful Plow, of which the following is a specilication.

This invention relates to sulky-plows, and it has particular reference to that class of sulky-plows which are provided with right and left plow members in order that the plow may traverse the field and turn about at the end ot' the furrow, turning' alternately a right and a left furrow, thus dispensing with the necessity of going' around the field, thus avoiding what is known as back or dead furrows and leaving' the land in level condition suitable for irrigation.

Among the objects of the invention are to improve and to simplify the construction ot' devices of the class referred to; to provide for the convenient adjustment of the transporting-wheels, whereby said wheels may be alternately raised and lowered, so that each wheel may be alternately used as a land-wheel and as a furrow-wheel; to provide improved mechanism for e`ectingl the adjustment of the plows and for simultaneously etfecting proper adjustment of an auxiliary supporting-wheel at the rear part ot' the trarne of the machine, said wheel being adapted to trav el in the furrow behind the earth-engaging plow, and to provide a construction which shall admit ot' both plow members being simultaneously placed in operative position, as for the purpose of opening' ditches for irrigation and the like.

ll'ith these and other ends in view, which will readily appear as the nature ot' the invention is better understood, the same consists in the improved construction and novel arrangement and combination of parts which will be hereinafter fully described, and particularly pointed out in the claims.

In the accompanying drawings has been illustrated a simple and preferred form of embodiment ot' the invention, it being, however, understood that no limitation is necessarily made to the .precise structural details therein exhibited, but that the rig'ht is reserved to any changes, alterations, and moditications to which recourse may be had within the scope of the invention and without de-f` parting from the spirit or sacrificing the etciency of the same.

In said drawings, Figure l is a top plan View of a sulky-plow constructed in accordance with the principles of the invention, the seat having been removed for the purpose ot' exposing the subjacent construction. Fig. 2 is a side elevation with the near wheel and the near plow member shown in dotted lines. Fig. 3 is a transverse sectional view taken on the line 3 3 in Fig. 2.

Corresponding parts in the several iigures are indicated by like characters of reference.

The frame of the improved plow is composed mainly o't` a transverse beam l, constituting' an axle and provided at the ends thereof with uprights 2 Q, said uprights or vertical members being' in the nature ot' guides and supports for the boxes 3 3, which are mounted to slide vertically thereon and which carry the spindles 4,11 pon which the transporting-wheels 5 are journaled. The boxes 3 arc connected by means of links 6 with a rocking bar 7, which is mounted pivotally upon a fulcrumpin 8, which is supported in a boxing 9, suitably connected with and supported by the axle l. One of the uprights or vertical members 2, preferably the one at the right-hand side ot' the machine, is provided at its upper end with a `forwardly-extending` bracket 1Q, upon which is formed a rack-segment 1l. Pivotally connected with the bracket 10 and concentric with the rack-segment l1 is a handlever 12, having an arm or crank 13, which is pivotally connected with one end ot' a link 14, the opposite end ot' which is pivotally connected with one of the boxes 3.

It will be observed that by manipulating the lever 12 the box 3, with which it is connected, will be moved upwardly or downwardly upon the upright 2, thus transmitting through the link 6 a rocking movement to the bar 7, whereby the movement is transmitted to the wheel carrying box 3 at the opposite side ot' the machine, thus causing' the transportingwheels to be raised or lowered with relation to the frame, it being' understood, ot' course, that when one wheel is raised the other wheel will be lowered. The hand-lever 12 is provided with a spring-actuated catch of ordinary construction, said catch being operated by means of a handle 16, suitably connected ICO with the lever 12. The latter may thus be retained at any desired adjustment, thus retaining the transporting-wheels securely in any position to which they may have been adjusted. It is thus obvious that either one of the wheels may be raised so as to constitute a land-wheel, while the other wheel is lowered so as to constitute a furrow-wheel. It is further evident that the adjustment of the wheels may be regulated and varied according to the depth of the furrow. It will also be seen that the two wheels may be adjusted to and supported at the same level, as for the purpose of transporting the machine from one place to another.

The axle member or main frame-beam 1 has been illustrated in the drawings as consisting of a vertically-slotted beam or casting, although this is not to be considered as an essential feature of the construction, inasmuch as a solid beam might well be used. Suitably connected with said axle or main beam are side pieces 17, the front ends of which are made to converge, the front extremities of said side members being spaced apart by means of a block 18, which is secured between said side members by a transverse bolt 19 or other suitable means. The block 18 is provided with forwardly-extending lugs 20, which serve in the usual manner for the attachment of the draft. The said block 18 is provided in the rear side thereof with a central slot or recess 21 and additional recesses 22 at either side of the central recess. Upon the bolt 19, which extends through the several recesses, are pivotally mounted the plow-beams 23, the forward ends of which are tted in the recesses 22. Fitted in the central recess 21 and engaging the bolt 19 is a longitudinal framebar 24, which extends rearwardly above the axle upon which it is supported and with which said frame member is connected by means of a clip 25 of suitable construction. The plowbeams 23 carry the plow members 26, one of which is of right-hand and the other of a lefthand pattern and which are mounted with their land-sides facing each other. The plowbeams and plow members may be of ordinary or of any well-known and approved construction.

The longitudinal frame member 24 has been shown as being provided with a rearwardlyextending bracket 27; but it is to be understood that this bracket may be integral with the frame-beam and that it actually forms a part of said frame-beam. The said bracket or frame-beam is provided at the rear end thereof with bearings for a vertically-disposed shaft 28, provided at its lower end with an arm or crank 29 and at its upper end with a cross-bar 30, which latter is preferably disposed approximately at right angles to the crank 29. The cross-bar 30 is provided at the ends thereof with upturued lugs 31. At or near-the outer end of the crank 29 is swiveled a shank 32, carrying a caster-wheel 33.

It will be observed that by rocking the shaft 28 in its bearings the crank 29 may be thrown either to the right or to the left side of the centerof thev machine. The casterwheel carried by and having swivel connection with said crank may be accordingly transferred from one side of the machine to the other, so as to travel in the furrow which is being turned by the earth-engaging plow member, or the said caster-wheel may be adjusted to travel centrally in the wake of the machine when the latter is being used for ditching purposes or is being transported from one place to another.

The frame of the machine includes upright members 34, which are four in number and which are spaced apart and connected with each other at their upper and lower ends by spacing members 35 36, which latter has been shown as being provided with acentral aperture 37, whereby it is mounted upon the longitudinal frame-beam 24, with which the upright members 34 are thus connected. Said upright members serve to support the seat 38, and the plow-beams 23 are confined between and guided vertically bythe outer and inner upright members 34.

Suitably connected with and supported by the frame of the machine, at either side thereof, are notched segments or rack-bars 39, conceutrically with which are pivoted hand-levers 40, having spring-actuated catches 4l engaging the said notched segments or rack-bars. Pivotally connected with the outermost upright members 34 are bell-crank levers 42, one at each side of the machine. The lower arms of these bell-crank levers are connected by means of links 43 with the hand-levers 40, and said lower arms are also connected by means of links or chains 44 with the upstanding lugs 31- of the cross-bar 30 upon the shaft 28, carrying the arm 29, with which the wheel-carrying shank 32 is pivotally connected'. The upper arms of the bell-crank levers 42 are provided with stirrups 45, supporting the plow-beams 23. The hand-levers 4() are connected with the frame of the machine by means of coiled springs 47, which when said levers are operated to set the plows into the ground are strained, so that when said levers are actuated to lift the plows from the ground they will assist in raising the weight of the plows. These springs are obviously especially useful when the connecting means between the bell-crank levers 42 and the crossbar 3() are temporarily removed, as will be hereinafter set forth.

The operation and advantages of this invention will be readily understood from the foregoing description taken in connection with the drawings hereto annexed. The trans- IOO IOS

ITO

porting-wheels are set by means of the adjusting-levers i2, according to the work that is to be performed, and the plows are likewise set or adjusted by means of the hand-levers 0, which latter, owing to the connection between the plows, which includes the links 43, the l bell-crank levers 42, the links 4A, and the cross-bar 30, Inust be operated simultaneously, as will be readily understood. This latter is an important consideration, inasmuch as owing' to the connections just described the weight of the plows will be equally balanced, and consequently but slight force will need to be exerted in order to effect the desired adjustment. Vhen the end of a furrow is reached, the plows are first adjusted to a common level. The machine is then turned in the direction of the land, which enables the turn to be made with comparatively slight strain upon the draft-team, and the wheels and the plows are then readjusted and placed in position for the return trip across the field. It will be observed that the caster-wheel 33 is adjusted with the plows and by the same mechanism. lVhen the plows are placed at the same elevation, the caster-wheel will occupy a central position in rear of the frame. Vhen either plow is lowered into operative position, the crank-arm 29 and the casterwheel will swing around into alinement with the plow, which is lowered for the purpose of tracking in the furrow made by said plow.

Then it shall be desired to use the machine for ditching purposes, the connecting means between the bell-crank levers 42 and the crossbar 3() are temporarily removed. The plowadjusting levers 4:0 may then be operated independently to set the plows at the desired level. ll'hen the machine is used in this manner-the caster-wheel will of its own volition travel centrally in the wake of the machine.
